To all 'whom it may concern:

Be it known that I, GEORGE R. McCann, a citizen of the United States, and a resident of Elkhorn, in the county of Walworth and Starte of Wisconsin, have invented a new and Imfpoved Pencil, of which the following is a l, clear, and exact description.

This invention relates to a pencil, and has for an object the revision of a pencil having a reillable lead) and means for feeding it'as used.

Fig.

Another object resides in the provision of" F ig. 2 isa transverse section on the line` 2-2 of Figure 1;` and l Fig. 3 is a section' on 'the line 3--3 of of the invention shown in the 1s a preferred form, although it The form drawings is understood that modifications in the construction and arrangement of the parts and in the character of` the materials used ma' be adopted without departing from the spint of rthe invention. l

The preferred. formI of the invention as shown in the drawings comprises a pencil barrel `1 'having a tapered lower end 2 and an open upper end threaded as at 4 and adapted to be closed by a flan cap 3 into the lowerface of whic a f .nut sleeve 5 is fixed. This sleeveextends downwardly within the barrel 1 and acts as a guide for a.

feed nut 6, the. shape of the nut preferablyv being hexagonal and vthe sections of the sleeve bein hexago/nal so that the nut can slip up an down within the sleeve but not rub therewithn. l

CA threaded feed screw extends downwardly within Ythe barrel l and passes through the nut 6. This feed screw, at its upper end, is in rthe form of a stem 8 through the cap 3 and embedded iir y within an operating thumb nut 10 between which and the collar 9 fastened on the screw 7 the stem 8 is firmly held. Dependent from the nut 6 on one side of the :feed screw 7 is a lead-feeder -rod 11 on the lower end of This lead holder is bent or offset from the feeder 11 so rthat` which is a lead holder 12.

the holder is in line with the screw 7 and the opening in the ltapered end 2. A. lead 13 is disposed in any suitable manner in the holder.

By the operating nut 10, the feed screw is rotated to cause the nut 6 to be moved up and down within thesleeve 5,

whereby the lead feeder 11 is moved downwardly or upwardly to advance or withdraw the lead 13.

It will be understood thatthis device is `exceedingly simple in its construction, involving the use of a minimum number of parts, capable of being economically assem- ,bled and yet being strong and durable; and

there are a minimum number of arts to get out of order and to be repair in operation. What I claim isz- A pencil, comprising a barrel havlng a tapering lower end, thev barrel for the' re' mainder ofthe length 'being 'o funiform di-A ameter'and having its upper end internally threaded, a flanged and threadedA ca and,

screwed into the upper end ofvthe b said cap 'having a central aperture, a polygonal sleeve in the barrel and' having its upper endA secured to the cap, a lfeed screwA having at its upper end a stem through the aperture of the cap, a thum i nut secured on' the end of 'the screw projecting through the cap',y a collar on the screw andy eng -the underside of the cap, a polygom on the screw, feeder rod secured tothe nut and carrying at its lower end a lead holder.
